Abstract

SAFER is a small six-axis maneuvering unit which attaches to the Space Shuttle spacesuit, and will be worn for self-rescue by all crewmembers performing EV As from Mir or International Space Station Alpha. SAFER was tested successfully on STS-64 in September 1994; as part of this test flight, linear acceleration and angular rate data was stored in a 12-MB on-board memory. The paper will present the results obtained from post-flight analysis of this data. In particular, the analysis has allowed the first experimental determination of the mass properties of a free-flying suited EVA astronaut.
